Topological Materials Creation Lab
Machine-translated · View original
A low-temperature physics lab that covers everything from crystal synthesis to measurement of physical properties.

AboutAbout the lab
Making new materials yourself and discovering new phenomena yourself.
The Topological Materials Creation Lab, part of the Low Temperature Physics Division at the Institute for Materials Research, Tohoku University, conducts broad research from crystal synthesis to measurement of physical properties.
The lab's motto is to "make new materials yourself and discover new phenomena yourself."
Launched in October 2025, the lab relocated equipment from Osaka University and is setting up synthesis equipment and equipment for controlling temperature and magnetic field one after another.
For graduate studies, the lab participates as a cooperating chair in the Department of Physics, Graduate School of Science. The lab's website presents it under the name "Sakai Lab."
Key terms
- Dirac electron materials
- Materials in which the effective mass of electrons becomes zero and the electrons' motion can be described by the Dirac equation
- Thermoelectric materials
- Materials that can convert heat and electricity into each other
- Multiferroic materials
- Materials that simultaneously have multiple kinds of order, such as magnetism and electrical properties
